Product Numbers SAY61.03U Proportional Control Actuator SAY81.03U Three-position Control Actuator Warning/Caution Notations WARNING: Personal injury or loss of life may occur if you do not follow a procedure as specified. CAUTION: Equipment damage or loss of data may occur if you do not follow a procedure as specified. Required Tools • 4 mm hex key, or 10 mm wrench • Flat-blade screwdriver or Phillips screwdriver to remove wiring compartment cover Expected Installation Time 30 minutes Wiring a factory-installed actuator 45 minutes Field replacement of actuator Prerequisites NOTE: Consult Technical Support if using with a TEC. WARNING : If mounting the actuator to a valve already in line, either close the shut-off valves in the piping (upstream first, then downstream) or switch off the pump to allow the differential pressure in the valve to drop.

Use earth ground isolating step-down Class 2 power supply transformers. Determine supply transformer rating by summing total VA of all actuators used. The maximum rating for a Class 2 step-down transformer is 100 VA. It is recommended that no more than 10 actuators are powered by one transformer. Parallel Control of Actuators SAY81.0-3U -Three-position actuators must have their own specific controller. SAY61.03U - Up to 10 actuators can be driven in parallel from a single controller output with a rating of 1 mA. Modulating actuators have an input impedance of 100K Ω. NOTE: Use either a Phillips head screwdriver or a flat- blade screwdriver to remove the wiring compartment housing cover for access to the terminal block and DIP switches. DIP Switch Setting (SAY61.03U only) Switch 1: Control Signal Select between 0 to 10 Vdc or 4 to 20 mA input signal for terminal Y (0 to 10 Vdc default). Switch 2: Flow Characteristic Do not change the flow characteristic switch. The proper flow characteristic is designed into the Siemens Pressure independent Control Valve. NOTE: Changing the default setting will modify a linear valve to a fast-opening characteristic. When set to default, the flow characteristic is determined by the valve body. Table 1. DIP Switch Settings.

Document No. 129-583 Installation Instructions January 4, 2016 Page 6 of 8 Siemens Industry, Inc. Manual Override Manual operation When pushing the manual adjuster down (1), it engages and the actuator can be manually operated. When turning the manual adjuster in a clockwise/counterclockwise direction (2), the actuator’s stem extends/retracts. See Figure 16. An overload protection prevents damage to the manual adjuster. Figure 16. Setting the position Upon actuation and locking the slide switch (see Figure 17), the manual adjuster remains engaged. When in this mode, do not turn the manual adjuster. Figure 17. Disengaging the setting When resetting the slide switch (see Figure 18), the manual adjuster returns to Automatic Mode. Figure 18. Commissioning and Operation Function Check and Calibration Mechanical Check Prior to making the function check, ensure that: • Actuator is mechanically connected to a Siemens Pressure Independent Control Valve. • Actuator is in Manual Operation mode. The actuator can be operated with the help of the Manual Adjuster. Manual Adjuster Action Actuator Response Turning in clockwise direction Actuator’s stem extends Turning in counter- clockwise direction Actuator’s stem retracts NOTE: Ensure that the actuator’s and valve’s stems are securely connected in all positions. If the actuator is forced to travel beyond its end positions, overload protection responds. Electrical Check Prior to making the function check, ensure that: • Actuator is mechanically connected to a Siemens Pressure Independent Control Valve. • Actuator is in Automatic Operation mode. • Actuator and, if required, accessories are correctly fitted and connected. • Power is applied. Calibration (SAY61.03U Only) Calibration is required with modulating actuators, and before the function check. Calibration must be performed manually. Prior to calibrating, ensure that: • Actuator is properly connected to a valve. • Housing cover is removed. • Power is applied. If required, calibration can be repeated any number of times. Document No. 129-583 Installation Instructions January 4, 2016 Siemens Industry, Inc. Page 7 of 8 To initiate the calibration process insert a flat-blade screwdriver into the calibration slot to short out the two sides of the slot. See Figure 19. Figure 19. Step 1—Bridge contact. During calibration, the actuator detects the valve’s end positions and files the exact stroke in its internal memory. Calibration takes place in three phases: • Actuator drives to H 0 (1), retracting actuator stem. Detection of upper end position. • Actuator drives to H 100 (2), extending actuator stem. Detection of lower end position. • The detected values are stored (3). Then the actuator follows the applied control signal. Observe the status indication (LED) during and after calibration. See Figures Figure 20 and Table 2. Figure 20. Step 2—Check LED. Table 2. LED Indication and Status. LED Indication Operating state Remarks, troubleshooting Green On Automatic mode Normal operation Blinking Calibration Wait until calibration is finished (then green or red light) In manual mode Manual adjuster in MAN position Red On Calibration error Start calibration again Blinking Detection of foreign object Check valve / actuator Off Off No power or electronics faulty Check operating voltage SAY61.03U Function Check Perform the function check for modulating actuators after calibration with a point test according to the following table: Table 3.
